set_service_autorenew

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden. It discloses that it's a 'plain write' with no immediate charge and not destructive, but omits details like response format, side effects if already enabled, or rate limits. Adequate but not comprehensive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences: the first states the core purpose, the second adds authorization and behavioral notes. No fluff, front-loaded, and every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple toggle with no output schema, the description adequately covers purpose and authorization. However, it does not explain what the caller should expect after invocation (e.g., success/failure indication) or prerequisites beyond the service_id. Adequate but not fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and the schema descriptions are already clear. The description repeats 'service_id from list_services' which adds no new meaning. Baseline 3 is appropriate as the schema handles parameter meaning.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool toggles auto-renew for a service, distinguishing it from sibling tools like get_service_autorenew (read) and other service actions (stop, reboot). The verb 'Toggle' combined with 'auto-renew' is specific and unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description mentions required scope 'services:write' and indicates the service_id comes from list_services, providing clear context. While it does not explicitly state when not to use it, the purpose is self-evident and alternatives are implied by sibling tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
